CellionaireBuy a pixel for one cent
Cellionaire is a public 1000×1000 pixel wall. Every empty cell costs $0.01, and a single cell is a valid order. No account and no sign-up.
What you need
- A wallet with a little USDC on Base or Solana. On Base, wallets such as Coinbase Wallet or MetaMask work; on Solana, wallets such as Phantom or Solflare. Keep a little ETH (Base) or SOL (Solana) for the network fee if your wallet does not cover it.
- About a minute to pick a cell and send the payment. The payment itself must be on the chain within 20 minutes of opening the order.
Steps
- Open cellionaire.com and click an empty cell (or a group of cells). You can also upload a small image, which is reviewed before it goes live.
- Pick a color, add your public display name, accept the Terms, and choose Base or Solana.
- Send the exact USDC amount shown, on the network shown, before the 20-minute deadline. Cells are not reserved while you pay: the first full payment we see holds the cells still free until it is confirmed. If someone else pays first, the order is not placed and the unused balance is refunded under the refund rules.
- After the payment is confirmed (usually under a minute), the cell appears on the wall.
Prices
- Empty cell: $0.01.
- A cell sold less than 24 hours ago: 2× its last price, rounded up to the cent ($0.01 → $0.02 → $0.04 and so on).
- 24 hours after its last sale, the price is back to $0.01. Anyone can take any cell by paying the current price; the previous owner is not refunded.
- A single cell is a valid order. Up to 20,000 cells per order.
Can I pay with a card?
Not directly. You need USDC in your own wallet on Base or Solana.
Can I pay from an exchange account?
Better not. Pay from your own wallet: refunds go back only to the address the USDC came from, and an exchange or a contract may not credit them. We cannot send a refund to a different address or network.
When does my cell appear?
After the payment is confirmed: on Base, after 12 blocks (usually under a minute); on Solana, after the transaction is finalized (usually under a minute). You must get the payment on chain before the 20-minute deadline shown on the order. A payment already on chain before that deadline can still complete if confirmation is slow.
Refunds?
Payments are final once your cells are live. If the order cannot be placed (for example someone else paid for a cell first), the unused balance is refunded only when the USDC confirmed for the order adds up to at least $1. The network fee is taken off the refund; if the fee would leave nothing, nothing is sent. Amounts under $1 are not refunded. See the Refund Policy.
